Claims (11)

  1. Structure de cylindre gainé (10) employée dans la fabrication d'un cylindre de machine à papier, ladite structure comprenant un noyau (16, 18) ayant une surface extérieure sensiblement cylindrique et un manchon (12) en matière polymère cuite,
    caractérisée par
    un manchon (14, 24) en matière compressible entourant ladite surface extérieure du noyau (16, 18),
    le manchon (12) en matière polymère cuite entourant ledit manchon (14, 24) en matière compressible.
  2. Structure de cylindre gainé (10) selon la revendication 1, dans laquelle la matière compressible comprend une matière inorganique.
  3. Structure de cylindre gainé (10) selon la revendication 1, dans laquelle la matière polymère est un époxyde.
  4. Structure de cylindre gainé (10) selon la revendication 1, dans laquelle la matière compressible est une silicone alvéolaire.
  5. Structure de cylindre gainé (10) selon la revendication 1, dans laquelle ledit noyau (16) comprend du carton.
  6. Procédé de formation d'une structure de cylindre pour une machine à papier, ledit procédé comprenant :
    l'application de matière compressible sur un noyau (16, 18) ayant une surface extérieure cylindrique pour former un manchon (14, 24) en matière compressible,
    l'application de matière polymère non cuite sur ledit manchon (14, 24) en matière compressible pour former un manchon en matière polymère et une structure de cylindre gainé; et
    un chauffage de ladite matière polymère suffisant pour cuire ladite matière polymère.
  7. Procédé selon la revendication 6, dans lequel ladite étape de chauffage a lieu pendant que ledit manchon en matière polymère (12) est contenu dans un moule préformé.
  8. Procédé selon la revendication 6, dans lequel la matière compressible est une silicone alvéolaire.
  9. Procédé selon la revendication 6, dans lequel la matière polymère est un époxyde.
